FAQ

Why did I build BullWatt?

I was bored by long loading time to ride in others apps. My goal is to get a fast way to launch an activity and record it. For me, a good session means working on wattage zones, which is why wattage control is the only option.

How it works?

Click on Start, then click on Connect, you could adjust your power with buttons or key arrows (up,down,left,right) that's it and don't forget to click on Stop to store the activity.

What is the FTMS?

Bluetooth FTMS (Fitness Machine Service) is a Bluetooth profile that enables standardized communication between fitness equipment and apps for data exchange and control.

How to export the activity recorded?

You could find all your sessions stored in TCX format. The last sessions are registered in your browser, there is no server side backup/save.

What are the requirements?

A computer with Google Chrome, a home trainer or an exercice bike compatible with Bluetooth FTMS and with the support of setting a target power (ERG mode= the resistance automatically changes in function of your cadence to deliver a constant wattage.).

My laptop or tablet is running on battery, how do I keep it from sleeping?

We use the same mechanism like Youtube to prevent sleeping, you have to keep the training tab visible, you can split your screen with split screen feature for example to watch Youtube or Netflix...

It doesn't detect my connected product!

Check the requirements, you could send me an email to discuss.
